Well, Eataly is open and everyone is going. No, I mean it, like the entire city of Chicago was inside the new River North Italian market after its grand opening Dec. 2. I ventured out this week to take a quick, single lap around the store, with the goal of finding the most expensive items I could spot. Here's what I found. (NOTE: If you bought everything in this gallery, it would cost $5,364.78 and you would feel happy and sad at the same time.) -- Mick Swasko
